“But this is no time to rest. Those who seek a fairer criminal justice system, unclouded by racial bias, must at a minimum demand that the government eliminate mandatory minimum sentences, which tie judges’ hands; rescind three-strikes laws, which often make no distinction between, say, armed assault and auto theft; amend “truth in sentencing” statutes, which prohibit early release for good behavior; and recalibrate drug policies, starting with decriminalization of marijuana possession and investment in substance-abuse prevention and treatment. Federal aid to state and local agencies, like the Edward Byrne Memorial Justice Assistance Grant and the Community Oriented Policing Services, must prioritize diversion and rehabilitation over arrest and incarceration.”
